[bug] Problem with closing bracket in a generated OpenCL kernel

[stratika]

Describe the bug

I noticed that one of the unit-tests that belongs to the white-list group, has a problem with a closing bracket only for the OpenCL backend. The PTX and SPIRV backends are working.

How To Reproduce

I have built TornadoVM as follows:

git checkout develop
./bin/tornadovm-installer --jdk jdk-21 --backend opencl && source setvars.sh

tornado --version

returns

version=1.0.7-dev
branch=develop
commit=4a2a072

Backends installed: 
	 - opencl

I ran the test06() test from the TestIf.java class, and got the output as follows:

tornado --jvm "-Xmx6g -Dtornado.recover.bailout=False -Dtornado.unittests.verbose=True " -m tornado.unittests/uk.ac.manchester.tornado.unittests.tools.TornadoTestRunner --params "uk.ac.manchester.tornado.unittests.foundation.TestIf#test06"

Test: class uk.ac.manchester.tornado.unittests.foundation.TestIf#test06
	Running test: test06                     ................  [FAILED] 
		\_[REASON] Bailout is disabled. 

Expected behavior

The expected behavior is to generate the OpenCL kernel which will be able to be built.

Computing system setup (please complete the following information):

• OS: Ubuntu 23.10
• OpenCL version: OpenCL 1.2
• Driver: n/a
• TornadoVM commit id: 4a2a072 from branch develop
